Hi

you can find the candidate release, with this feature here:

http://rap.dsi.unifi.it/~bettini/gengetopt-2.22.2.tar.gz

any feedback is more than welcome :-)

now the generated header looks like this

#ifndef CMDLINE_PARSER_PACKAGE
/** @brief the program name (used for printing errors) */
#define CMDLINE_PARSER_PACKAGE PACKAGE
#endif

#ifndef CMDLINE_PARSER_PACKAGE_NAME
/** @brief the complete program name (used for help and version) */
#ifdef PACKAGE_NAME
#define CMDLINE_PARSER_PACKAGE_NAME PACKAGE_NAME
#else
#define CMDLINE_PARSER_PACKAGE_NAME PACKAGE
#endif
#endif

and CMDLINE_PARSER_PACKAGE_NAME is used (if not empty) to print --help 
and --version, while CMDLINE_PARSER_PACKAGE is used for printing errors.
